The 10 Best Dive Computers Every Underwater Junkie Should Own

Exploring the underwater world is exhilarating, and those who have tried it once typically go back for more. It, therefore, comes as no surprise, then, that scuba dive is soaring in popularity each year. While it’s a thrilling experience, it’s in an unknown area.

So, it’s essential to take safety precautions, such as investing in the best dive computer, as you embark on your underwater adventures.

Doing so will allow you to monitor important information as you explore the deep blue sea. After all, when you’re underwater, you can easily get disoriented, lose direction, and not know your current depth, particularly for beginners.

With this handy gadget, you can avoid decompression sickness as it will effectively log your dive. In today’s digital era, the best dive computer comes in the form of a sleek, lightweight watch strapped to your wrist, ideal for everyday use.

But, with the wealth of options that have littered the market, selecting the ideal option can be an uphill battle. To the unfamiliar eye, they all look the same.

Luckily, you’ve come to the right place as we’ve rounded up the top 10 picks that will take your dive experience to the next level.

Buying Guide: How to Choose the Best Dive Computer

Armed with the knowledge on the top 10 dive computers that will give you value for your money, let’s explore the key buying factors to consider.

Oxygen Blend

There is a soaring number of divers that are opting for greater oxygen blends to boost their underwater performance and resist fatigue after their dive sessions. So, if taking on these new challenges piques your interest, then it’s a no-brainer. You need a dive computer that’s a beast in juggling several gas blends. For a myriad of recreational divers, two gasses with up to 50% oxygen is abundant. However, advanced divers will want a model that can handle a blend of up to 8 gasses along with Trimix and 100% oxygen.

Display Type

A plethora of entry-level dive computers use an ELD or black and white LCD backlit screen. These displays use easy-to-read, bold digits for better visibility in direct sunlight and low light. Backlit screens typically utilize phosphor-luminescent technology to illuminate and maintain a glow after shining a dive torch on them.

So, even if the device’s backlight malfunctions, you can still read the screen display. Full-color screens are increasingly popular courtesy of their in-depth displays and visual allure. But remember, these types of screens are challenging to read in direct sunlight and bright light. And they’re more fragile. So, if you’re a beginner, a basic dive computer will get the job done.

Number of Buttons

If you’re a newly certified diver, it’s advisable to opt for a dive computer with as few buttons as possible. Granted, superior models come with up to 5 buttons; newbies may find them hard to juggle and can be confusing underwater.

But basic designs are easier to navigate and won’t leave you disheartened mid-dive. For professional divers with more experience using advanced models, this buying factor is less important.

Operating Modes

A multitude of entry-level dive computers come with fundamental modes such as the Nitrox and Air. You’ll also find a gauge that monitors your bottom time and depth without factoring in your no-decompression limits. Advanced models include options such as a watch that allows your dive computer to double as a wristwatch and free-dive.

High-end designs that are well over $500 include advanced functions such as Trimix and re-breathing. So, if you’re up for different dive challenges to hone your skills, then you’ll require at least two computers to add a layer of safety and redundancy. Remember, a basic model is a great starting point before advancing to the pricier advanced models down the road.

Battery Type

If your dive plans revolve around remote and exotic destinations, then a dive computer that demands professional servicing when the battery runs low is a recipe for frustration. Select a product that has a rechargeable battery or one that’s user-changeable to avoid resigning yourself to this fate.

Compatible Technology

Look for dive computers that perfectly sync with smartphones and tablets (iOS and Android-powered) and PCs to log and plan your dives. While some entry-level models use USB linking, the more advanced dive computers use Bluetooth.

Wireless Air Integration

The best dive computer uses Wireless Air Integration that’s synced to a Bluetooth transmitter mounted to the first stage of your regulator. It’s this external sensor that relays pressure to the mounted display, where’s readable.

Wireless transmitters usually don’t come with dive computers, which means you’d have to shell out extra bucks. Furthermore, they’re fragile gear that’s susceptible to damage. Nonetheless, seasoned divers concur that they’re well worth the extra cost.

Adjustable Dive Profile

A dive computer computes your no-decompression limits by using formulas known as algorithms. It gives you free rein to personalize your dive profile in a conservative and mathematical model depending on your experience level and comfort. Even the most liberal dive profiles guarantee your safety and well within your capabilities. And it can aid in scoring additional minutes underwater.

Optional Added Deep Stop

If you’re a beginner, then deep stops are the least of your worries. However, if you’re aiming to explore deeper, then your dive computer may recommend extra stops amidst your ascent.

With the addition of stops to your driving profile’s suggested ‘safety stop’ at 5 meters for 3 minutes, your body gets adequate time to expel the nitrogen in your tissue. Doing so curbs the likelihood of decompression sickness and injury.

And, it ushers in a safer trip back to the water surface. The best dive computer allows you to remove or add these stops that trigger a more or less conservative dive profile.

Residual Nitrogen Reset

In some dive computers, you can entirely reset the memory between dives. As a result, they can be shared by different divers per day without the need to account for previous dive profiles. So, this is an essential factor to consider if you’re buying a dive computer as rental equipment for clients or students.

Several Gasses In One Drive

If your goal is to make decompression stops during your dive sessions, then it’s essential to use at least two gas blends while underwater. By incorporating a 2^nd gas whose percentage surpasses that of oxygen, your body can release unwanted nitrogen in a jiffy. It’s this quicker ‘off-gassing’ that lowers the amount of time required for safe ascents.

Cold Water Compatibility

A dive computer that’s built with cold water in mind incorporates unique and user-friendly features. So, if you want to take the plunge into icy conditions, ensure you choose a product with oversized buttons that are easy to press with thick gloves on. Moreover, you’ll require a long wrist strap that’s a snug fit over a dry or wet suit.

To Wrap It Up

Delving into the underwater world is something everyone should experience at least once in their lifetime. And some become hooked to the majestic underwater life after their first experience.

But, for much-needed peace of mind, it’s essential to take as many precautions as you can while you delight in the thrill.

Fortunately, with the best dive computer, you’re assured of an exhilarating and safe underwater experience. So, order yours today!
